PERROR(1)

NAME
perror - display MySQL error message information

SYNOPSIS

perror [options] errorcode ...

DESCRIPTION

For most system errors, MySQL displays, in addition to an internal text message, the system error code in one of the following styles:

    message ... (errno: #)
    message ... (Errcode: #)

You can find out what the error code means by examining the documentation for your system or by using the perror utility.

perror prints a description for a system error code or for a storage engine (table handler) error code.

Invoke perror like this:

    shell> perror [options] errorcode ...

Examples:

    shell> perror 1231
    MySQL error code 1231 (ER_WRONG_VALUE_FOR_VAR): Variable '%-.64s' can't
    be set to the value of '%-.200s'

    shell> perror 13 64
    OS error code  13:  Permission denied
    OS error code  64:  Machine is not on the network

To obtain the error message for a MySQL Cluster error code, use the ndb_perror utility.

The meaning of system error messages may be dependent on your operating system. A given error code may mean different things on different operating systems.

perror supports the following options.

    • --help, --info, -I, -?

    Display a help message and exit.

    • --ndb

    Print the error message for an NDB Cluster error code.

    This option is deprecated in NDB 7.6.4 and later, where perror prints a warning if it is used, and is removed in NDB Cluster 8.0. Use the ndb_perror utility instead.

    • --silent, -s

    Silent mode. Print only the error message.

    • --verbose, -v

    Verbose mode. Print error code and message. This is the default behavior.

    • --version, -V

    Display version information and exit.
